Abstract (en)
A method for producing a salt of an amine with a cyanoalkenylcyclopropanecarboxylic acid, the method comprising a first step of mixing a carboxylic acid compound represented by formula (2C) and at least one amine selected from the group consisting of primary amines and secondary amines in an organic solvent; a second step of depositing a salt of the amine with a cyanoalkenylcyclopropanecarboxylic acid represented by formula (2) from the mixture obtained in the first step; and a third step of recovering the salt deposited in the second step; wherein, R represents an alkyl group optionally having a substituent or a halogen atom.
